在128*128的网格上求解2维波动方程来模拟大范围的水波。用一个像素渲染程序完成对波动方程的时间积分，结果存放于一个浮点数纹理中，.然后将此纹理传给渲染模块。此外使用凹凸贴图来描述水面的细节波纹，这会给稍后的逐像素渲染带来逼真的水面闪烁高光效果.-128* 128 grid on the solution of 2-dimensional wave equation to simulate a wide range of water. With a pixel shader program

一个利用法线贴图实现模型细节的Demo,凹凸纹理贴图运行程序。-The realization of a model for the use of normal mapping details of the Demo, run the program bump texture mapping.

自己写的多边形点在内判断的简单算法，运行没有出现问题，无论多边形情况（凹凸）-Write your own polygon points in a simple algorithm to determine, running no problems, regardless of polygons situation (bump)

本算法基于凹凸轮廓对字符图像进行切割，能解决复杂背景下的字符切分-The algorithm based on the bump outline of characters cutting image, can solve complex background character segmentation
